User localization using friend location information |
| 摘要 |
A method, system, and medium are provided for refining an estimated location of a user using an accurate location associated with a friend of the user. A location of the user is estimated with a first level of accuracy, and the friend of the user is identified. A location of the friend is determined with a level of accuracy greater than that of the user's location. A probability that the user is near the friend is determined, and when the probability exceeds a predetermined threshold, the friend's location is used to refine the user's location. |

1. Computer-storage media having computer-executable instructions embodied thereon that, when executed, enable a computing device to perform a method of refining an estimated location for a user using an accurate location associated with a friend of the user, the method comprising:
estimating a location of the user, wherein the location of the user has a first level of accuracy; identifying the friend of the user; determining a location of the friend, wherein the location of the friend has a level of accuracy greater than that of the location of the user; determining a probability that the user is near the friend; and when the probability exceeds a predetermined threshold, utilizing the location of the friend to refine the location of the user. |
